Cox Communications is lowering Internet upload speeds in entire neighborhoods to stop what it considers "excessive usage," in a decision that punishes both heavy Internet users and their neighbors.

Cox, a cable company with about 5.2 million broadband customers in the United States, has been sending notices to some heavy Internet users warning them to use less data and notifying them of neighborhood-wide speed decreases. In the case we will describe in this article, a gigabit customer who was paying $50 extra per month for unlimited data was flagged by Cox because he was using 8TB to 12TB a month.
